fabric是的一个基于命令行的自动化部署框架,用docker开了两个容器来学习fabric.

#!/usr/bin/env python
#-*- coding=utf-8 -*-
from fabric.api import *
env.hosts=[
  'root@114.215.86.228:22',
  'root@114.215.86.228:32',
]
env.passwords={
  'root@114.215.86.228:22':'*****',
  'root@114.215.86.228:32':'***',
}
@task
def task1():
  run('ps')
@task
def task2():
  run('uname -a')
@task
def dotask():
  execute(task1)
  execute(task2)

执行结果

尽管如此,密码是明文,不安全,因此仍然推荐用加key的方式管理。
